Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

Yeah I plan to get a wide band in the next coming weeks and use that for tuning, I was just curious if there was anymore useful input with my current situation.

Do these numbers sound pretty good for AFRs?
WOT: 13.0>
Cruise: 14.5-15.0
Idle: 15.0

I've been basing my jetting off of what the plugs tell me and how the exhaust smells, but I think with the right PV I can get away with running 64 primaries. It does fine under mild acceleration but started to get a little surgey when I put my foot down a little (coincidentally right around 9 inches of vacuum.) which is why I ordered a 9.5PV. I know every engine is different, but the fundamentals are the same which is what I'm trying to get a grasp of here.
